hi, do you know if we can use coroutines with JS/IR in TypeScript? From what I see we cannot use suspend functions, but with Flow I've got d.ts result like: longAdd(a: number, b: number): kotlinx.coroutines.flow.Flow<number>; . Any idea if we can use it?

You still can't. You'll need a suspend function to collect the flow. However you can expose a promise and use that from Typescript

[Mikołaj Kąkol]

tried that, but when exporting:

@JsExport
fun fooPromise(): Promise<String> = GlobalScope.promise {
    delay(2000)
    "sth"
}

I've got d.ts as:

export function fooPromise(): kotlin.js.Promise<string>;

which doesn't seem to work

or maybe I need to add kotlin.js.Promise dependency to TS project

[andylamax]

That looks like a bug. You should file it

[Mikołaj Kąkol]

fun thing, when I just removed kotlin.js. before Promise i d.ts it works

[Mikołaj Kąkol]

works, like I can use this promise
